CAN-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 754,940, dated 'March 15, 1904. Application led April 26, 1902. Serial No. 104,870. (No model.)

To a/ZZ whom it may concern,.-

Be it known that we, JOHN G. REHFUss and MARTIN O. RnHFUss, citizens of the United States,r esiding at Philadelphia, in the county of PhiladelphiaJ and State-'of Pennsylvania, have invented certain new and useful Improvements in Can-Making Machines; and we do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in can-making machines; and it consists in the provisionv of means whereby sheets of tin are automatically fed into the machine, said sheets being cut into strips each the width of the length of the body portion of a can, after which the tops and bottoms are automatically stamped out of the end pieces of the strips, then the waste ends of the strips from which the tops and bottoms are cut being cut oif, and afterward the ends of the strips are crimped to form the ends, which are afterward interlocked, forming a seam, and in the provision of means whereby the crimped strips are turned about the former and their ends interlocked, clenched, and thence fed to another part of the machine, where the seams are automatically soldered preparatory to their being carried to another part of the machine, where the tops and bottoms are automatically applied to the body portions of the cans by apparatus which is shown and described in our former application, Serial No. 97,907, iiled March 12, 1902.

rlhe invention consists, further, in various details of construction and combinations of parts, as will be hereinafter fully described and then specifically defined in the appended claims.

Ourinvention is illustrated in the accom panying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings- Figure 1 is a side elevation of a portion of our improved apparatus for making the body on the former.

portions of cans and tops and bottoms therefor. Fig. 2 is a side elevation of a portion ofthe inachine which is continuous with the form of mechanism illustrated in Fig. 1; and Fig. 3 is also a side elevation of a portion of the machine which is continuous with Fig. 2, the three views, Figs. 1, 2, and 3,.taken together, showing the entire side elevation of our mechanism for making the body portion of a can and the tops and bottoms therefor.

Fig. 22 is a longitudinal section centrally through the receptacle for holding the pile of tin and the carriage on which the pile is fed forward. Fig. 23 is a vertical sectional view through the clutch mechanism. Fig. 24 is a top plan view of a portion of the machine, showing the guide mechanism for holding the strips, while the tops and bottoms for the cans are punched therefrom and the strips sheared; and Fig. 25 is a side elevation of the mechanism illustrated in Fig. 24C, showing the means for holding the strips truly while being operated upon. Figs. 26, 27, and 28 are views which when taken together form a continuous side elevation of the apparatus embodied in the present application, portions being shown in section and parts of the frame of the machine not being shown in order to better illustrate the operative features of the apparatus. Fig. 29 is a detail view showing the levers for pushing the can-bodies on the former. Fig. 30 is a detail of the member for pushing the can-bodies off the end of the former. Fig. 3l is a horizontal sectional view looking down upon the table of the machine and showingthe manner in which the waste ends .of the strips are disposed of and showing the positions of the dies and the crimping members with relation to other parts of the machine. Fig. 32 is a sectional view looking upward, taken in the same plane.

Reference now being had to the details of the drawings by letter, A designates the main operating-shaft of the mechanism, which may be driven from any source of power and is suitably journaled in bearings. Mounted on theupright portion of frame A is a table A2, and journaled in suitable bearings in apertures at intervals along said table are antifrictionwheels A2, which are stationary, and A1 designates a slide or carriage adapted to rest upon and work longitudinally and horizontally on shoulders A5 of the table, and on said carriage a pile of sheets of tin is adapted to be placed at the cut-away portion A11. The upper ends of said antifriction-wheels A2 project aslight distance above the upper surface of the table and the slide or carriage for the purpose of relieving the carriage of a portion of the weight of the pile of tin, and consequently minimizing the amount of friction between the pile of tin and the table.

Mounted loosely upon the shaftA isa wheel B', to which a clutch-wheel B3 is connected, said wheel B having a cam-groove B2 in its circumference, in which an antifrietion-roller B12 travels, which antifriction-roller is carriedV by the lever B211, which is pivoted at B21 to the frame and also to a link B22, which in turn is pivoted at B23 to a bracket integral with the carriage or slide A1. (Clearly shown in Figs. 3

and 23.) Said clutch-wheel is adapted to be normally idle, excepting at each rotary movement of a worm-wheel B111, at which time clutch mechanism is actuated so as to cause the wheel B8 to make a complete rotary movement, for a purpose which will-presently appear.

B'1 designates a clutch-operating arm which is operated by means of the oscillating lever B1 for the purpose of throwing the clutch mechanism into or out of engagement with the clutch-wheel, accordingly as it is desired to cause the wheel B with the cam-groove therein to rotate or remain stationary. Said lever B5 is journaled on a shaft B1, mounted in the frame of the machine, and one end is hooked, as at B7, and is designed to fall into the notch B11 in the circumference f the wheel B2 each time the latter makes a complete revolution. Mounted to rotate with said wheel B9 is a gear-wheel B11), having a series of teeth about its circumference, preferably one hundred, so that one hundred sheets of tin may be fed forward before a new pile is brought forward to locations to be underneath mechanism whereby the sheets are picked up singly. A worm B11 is mounted to rotate with the main operating-shaft and is in mesh with the teeth of said wheel B1. A wheel B12 is mounted to rotate with the shaft A and has a camgroove B13 about its circumference, in which the antifriction-roller B11 travels, which antifriction-roller is mounted on a stub-shaft adjacent to the lower end of the arm B15, which is fixed to the shaft B11, whereby said arm B15 at each rotary movement of the operating'- shaft will cause the shaft B1, to which itis fastened, andalso the arms B111, to rock, said arms B111 being fixed to the shaft B11. rlhe pushingfingers B17, which are fastened to a cross-piece B111, Fig. 6, which are mounted on -the ends of the arms B111, will cause the sheet to be fed forward after the latter has been raised. to a suitable position to be -fed forward by means which will be hereinafter described, and said fingers will be returned to theirstarting position.

Mounted to have a vertical movement in suitable boxings on the opposite sides of the frame of the machine are reciprocating rods or bars C, which are connected at their upper ends to a cross-piece C', which has laterallyprojecting bars C2, each of` which at its ends is provided with a suction-cup or magnet C12, which are adapted as said strips are thrown into contact with a sheet of tin to raise asheet from the pile of tin and hold the same suspended until it is pushed forward by said feeding-{ingers. A spring C1 is interposed between a stationary collar C5 and a collar C, which is fastened to the rod C, which is provided for the purpose of holding the cups or magnets. for raising the sheets of tin normally against the pile of sheets of tin which have been previously fed forward to a position underneath IOO IIO

the apparatus for raising the sheets singly. An arm C7 is fixed to a shaft C8, mounted on the frame of the machine, and one end of said arm C7 is pivotally connected to the lower end of thc rod C at C, the lower portion of said rod passing through a suitable guide-box C10.

D designates a Wheel mounted on and adapted to rotate with the shaft A and having a cam-groove D' about its circumference in which groove an antifriction-wheel D2 travels, which latter is mounted on astub-shaft carried by the arm D3, which is fixed to and adapted to rock the shaft C, whereby at each revolution of the wheel D the mechanism for raising the sheets of tin is depressed against the upper sheet ofthe pile and raised to its highest throw.

In order to hold a sheet of tin which has been raised from a pile (designated in the drawings by the letter E,) in a horizontal position in readiness to be pushed forward between friction feed-rollers, whereby the sheet is fed to another part of the mechanism, we provide a rock-shaft F, which is journaled in suitable bearings F, there being one of said shafts on either side of the machine, and fixed to the end of said shaft F is a bevel-gear F2, which is in mesh with the bevel-gear F3, journaled on a shaft Ff, mounted in the frame of the machine. Said shaft F4 has keyed thereto an arm F5, which is pivotally connected to a rod F, carrying at its lower end a stub-shaft F7, on which is journaled an antifriction-Wheel F8, adapted to travel in a groove Fg on the cam-Wheel F10, which latter is fixed to rotate with the operating-shaft A. Fixed to said rock-shaftF are two collars F, each of which has an integral arm F12, the upper end of which is provided witha right-angled bracketplate F13, which projects atright angles from said arm F12 a slight distance, these plates being provided for the purpose of supporting the sheets of tin by the two plates on each side of the sheets being driven toward each other sufficiently to catch under the edges of the sheet to hold the sheet while it is being pushed forward by means of the fingers B17. By reason of the peculiar outline of the cam-groove in the wheel F10 the parts are so operated that the said plates F13 will have performed their office and be swung or rocked outwardly, so as to clear the path for the next sheet of tin which is raised by the mechanism which has been described.l

G and G' designate friction feed-rollers between which the sheet of tin is fed forward to a position upon the machine where the sheet is cut into strips of a width equal to the length of the body portion of a can. One of said rollers, G, is mounted on a shaft G2, which carries a bevel-gear G3, which is in mesh with a bevel gear-wheel G4, which is fastened to rotate with the shaft G5, mounted in suitable bearings on the frame of the machine. By.

means of the adjusting-screw G the tension between the rollers G and G may be adjusted.

Mounted in bearings H in the frame of the machine is a vertically-rotating shaft H', having a bevel-gear H2 fixed upon its lower end, which is in mesh with a bevel gear-wheel H3, mounted upon and adapted to rotate with the operating-shaft A, and at the upper end of said shaft H is secured abevel-gear Hi, which is in mesh With a bevel-gear N, fixed upon the shaft M. A second gear-wheel NX, also fixed upon the shaft N, is in mesh with the gear H5, secured to a shaft H, mounted inv the frame of the machine. Saidgear-wheel H5 is in mesh with a gear H7, secured to rotate with the shaft H8. Said gear H7 is in mesh with gear fixed to a shaft H13, which latterhas also mounted to rotate therewith a bevelgear H. Referring to Fig. 3, it will be seen that bevel-gear H9 is in mesh with bevel-gear H1", which is fixed upon shaft G5, that drives, through the gear connection, the friction feedroller G. Bythis intermcshing gear mechanism just described it will be observed that motion is imparted from the main operatingshaft to the friction feed-roller G, whereby the sheets of tin are fed singly to the part of the mechanism where the sheets are cut into strips preparatory to having the tops and bottoms of the cans punched out of the ends thereof. l

Referring to Fig. 2 of the drawings, I, I', and 12 designate three shafts which are journaled in suitable bearings adjacent to the upper marginal edges of the frame of the machine, and mounted upon and rotating with the shaft I2 is a cam 13, about the circumference of which a strap I* travels, which has an integral arm I5, which is pivoted, by means of a pin I, to an arm 17, integral with or secured to a reciprocating knife IS, which is mounted to reciprocate vertically in the frame. The

IOO

cutting or shearing edge of said knife is designated by letter I and is adapted when at its lowest limit to shear with a stationary cutting-knife IX, Fig. 25, over which the sheet of tin is fed forward. Africtional feed-roller H is mounted upon the shaft H13 and is adapted to rotate therewith, and a second friction-roller H12 is mounted in a suitable adjustable boxing H20 and adjacent to said friction-roller on shaft H13 and between which the sheets of tin are fed immediately before being cut into strips to form the body portions of cans. Two sets of friction-rollers (designated, respectively, by letters J, J J 2, and J 3) are provided, which rollers J and J 3 are mounted in adjustable boxes, and the roller J is driven by a gear connection. with the Wheel H7, while the friction-roller J is driven by gear connection with the wheel J 4, which is in mesh with the roller J.

Fixed to the shaft 12 is a gear-wheel K, which is in mesh with a gear-wheel K, fixed lIO
